摘要
本文通过对北京十三陵地区从元古代到中生代地层的古地磁测试和数据分析,结合区域地质特征,证实了燕山运动中期在燕山西段形成的一系列推覆构造,其推覆体都是邻近的地质体,并非远方的客体,推覆距离为几公里至数十公里,推覆方向由南向北。
This paper presents a test the paleomagnetism of the strata of shisanling area ranging from Proterozoic Era to Mesozoic, and a analysis of the data obtained, Considering the regional geological feature, the paper concluded that a set of nappe structures take shape in the western part of Yanshan Mountain during the middle of Yanshan Movement. The nappe did not come from areas in distance but from adjacent strata. The distance of the nappe movement ranges from several kelometers to some ten kelometers, and in the direction from south to north.
